> Right now with large region count tables, the write buffer is not efficient.
> This is because we issue potentially N RPCs, where N is the # of regions in
> the table. When N gets large (lets say 1200+) things become sloowwwww.
> Instead if we batch things up using a different RPC and use thread pools, we
> could see higher performance!
> This requires a RPC change...
